RTP-MIB Table View

Maps rtpSessionDomain, rtpSessionRemAddr, and rtpSessionLocAddr
TAddress pairs to one or more rtpSessionIndex values, each
describing a row in the rtpSessionTable.  This makes it possible
to retrieve the row(s) in the rtpSessionTable corresponding to a
given session without having to walk the entire (potentially
large) table.

rtpSessionInverseEntry row .1.3.6.1.2.1.87.1.2.1

Each entry corresponds to exactly one entry in the
rtpSessionTable - the entry containing the tuple,
rtpSessionDomain, rtpSessionRemAddr, rtpSessionLocAddr
and rtpSessionIndex.

Maps rtpSenderAddr, rtpSessionIndex, to the rtpSenderSSRC
index of the rtpSenderTable.  This table allows management
applications to find entries sorted by rtpSenderAddr rather than
sorted by rtpSessionIndex.  Given the rtpSessionDomain and
rtpSenderAddr, a set of rtpSessionIndex and rtpSenderSSRC values
can be returned from a tree walk.  When rtpSessionIndex is
specified in the SNMP Get-Next operations, one or more
rtpSenderSSRC values may be returned.

Maps rtpRcvrAddr and rtpSessionIndex to the rtpRcvrSRCSSRC and
rtpRcvrSSRC indexes of the rtpRcvrTable.  This table allows
